Title: Automatic feed-take-out device in press machine
Inventor: AKUTSU SHINICHI
IPC: B21D43/10
Filed: 1979-05-04
Abstract: PURPOSE: To prevent the damages of materials owing to the malfunction of their feeding and taking-out and save the manpower for work by providing forward- backward openable grips to the right and left of the press machine and a vertically movable work setter below the same, and associating their operations to the press.  
     CONSTITUTION: At the ascending of a ram 26, the take-out side grip 12 advances in an opened state toward above a die 1 and descends. At this time, the grip 12 on the feed side descends in the opened state in the retreat position and at the same time a work setter 24 ascends, so that the material is pushed up and may thus be sandwiched. Next, upon ascending of the take-out side grip 12, it closes to sandwich the material above the die 1 and retreats and descends, then the grip 12 opens to drop the material. On the other hand, the feed side grip 12 closes upon starting of ascending to sandwich the material on the work setter 24 and advances and descends, then the grip 12 opens to place the material on the die 1. At this time, the work setter 24 descends upon ascending of the foregoing feed side grip 12 to send the material from the conveyor 25. Next, when the both grips 12, 12 are in the retreat positions, the material is worked by a punch 27.

IPC: F24H9/00
Filed: 1989-03-07
Abstract: PURPOSE:To improve an efficiency of the heat exchanger and make a compact heat exchanger by a method wherein a length of each of resistors within smoke tubes located far as viewed from a burner arranged on a side wall part of a combustion chamber is shortened and a length of each of inhibitors within each of the smoke pipes placed at an operator's side is elongated. CONSTITUTION:Combustion gas generated from a burner 3 arranged at a side wall of a combustion chamber 1 strikes against an opposing water boiler wall 2, its direction is changed to face upwardly and then the combustion gas passes through some smoke pipes 4. The combustion gas flowing within the smoke pipes 4 placed far as viewed from the burner shows a higher temperature and the combustion gas at the operator's side shows a lower temperature. Accordingly, in compliance with a temperature distribution of this combustion gas, the lower end position of each of the resistors 5 within each of the smoke pipes 4 far as viewed from the burner is high to provide shorter resistors. As a result, a length of each of the resistors 5 is lengthened in order that the lower end position of each of the resistors 5 within the pipes 4 placed at the operator's side as viewed from the burner is lower, an efficiency of a heat exchanger can be improved without providing any upgrading of the material of each of the resistors and without increasing a size of the heat exchanger.

IPC: G03F7/095
Filed: 1982-03-31
Abstract: PURPOSE:To form a minute pattern with a high accuracy, by carrying out the formation of a pattern while leaving a photosensitive resin film high in developing speed. CONSTITUTION:First of all, photosensitive resin films having different developing speeds with respect to the same developer are provided on a semiconductor substrate 11 in order from the film highest in developing speed to form a multiplicity of layers 12-14. Then, the layers 12-14 are selectively exposed and are processed by the same developer to form a predetermined pattern. Since the layer 12 having a high developing speed is formed on the substrate 11 into a predetermined thickness, the selective irradiation time can be reduced. In addition, the irradiation amount is permitted to be constant regardless of the thickness difference between the resin films on the substrate 11 having a step. Accordingly, a minute pattern can be formed with a high accuracy regardless of the kind of the substrate and the step thereon.

Then a command if received is executed as long as those received data are confirmed. While the initialization is carried out when the key input is confirmed together with input of a reset switch 67. In a reception mode of a reset command, a reset command is delivered to a scanner 200. While the reset signal is sent to the scanner 200 for execution of the initialization when reception of the reset command is impossible. Thus a scanner is also initialized at the host side just by outputting a reset command to a picture information output device 100.

Title: Method and device for separating continuously oxygen from air
Inventor: FURUKAWA TAKESABUROU
IPC: B03C1/00
Filed: 1984-03-22
Abstract: PURPOSE:To separate continuously and highly efficiently oxygen from air by making use of the phenomenon that the magnetizing rate of oxygen is highest in air and that only the oxygen is strongly magnetized and attracted to a magnetic field and acting the air to the magnetic field. CONSTITUTION:When a piston 4 is moved downward, air is taken into a cylinder 1 through an air intake solenoid valve 2. Oxygen molecules are attracted to the magnetic field of a casting magnet 6 and form a layer in the gas with the gas except oxygen. When the piston 4 is moved upward, the oxygen molecules which are held attracted to the magnet 6 move until the valve 2 is changed over to act as a discharge valve. The valve 2 is closed to shut off the outdoor air when the gas except oxygen is discharged; at the same time, an oxygen solenoid valve 3 opens so that the oxygen is injected into an oxygen tank by an oxygen suction pump. One cycle of operation is thus completed. Such devices are provided in multiple stage in series to increase the content and yield of oxygen.

Abstract: PROBLEM TO BE SOLVED: To reduce the fretting wear in a mechanical member by forming an Fe-Al alloy covered layer on a surface layer part of a contact surface of two members which are brought into contact with each other in a close fitting manner. SOLUTION: A tapered hole part 4 corresponding to a tapered surface of a shank part of a tool holder is provided in a tapered sleeve 1 of a mechanical structure such as a machine tool in which the relative motion is generated between contact surfaces of members which are brought into contact with each other in a closely fitting manner. The relative motion is generated between the tapered surfaces of the shank part and the tapered hole part 4 due to fluctuation of the vibration and stress during the cutting, which causes the fretting. Al is diffused on an inner circumferential surface of the tapered hole part 4 of the tool holder and on at least one surface layer part of the tapered surface of the shank part by the surface treatment method to form an Fe-Al alloy covered layer.  Aluminum oxide is generated on the Fe-Al alloy covered layer by the heat generated in the relative motion between the contact surfaces to prevent the fretting wear.
